folderify Option for smaller .icns filesize

Option for smaller .icns filesize

e.g. leave out @2x Retina versions, except maybe 512x512.

Possibly run through a compressor (pngcrush? What does .icns use internally?)

It appears that above 32px, the @2x version of a particular resolution is the same as the (regular) next resolution.

Using pngcrush on the input files didn't seem to reduce the output filesize, but removing redundant files did.

While the 128x128@2x image is the same as the 256x256 image, leaving out the former results in pixelated upscaling.

I've tested this again.

Removing the Retina version of a redundant resolution results in blurriness: Screenshot 2023-04-04 at 03 17 41

Removing the non-Retina version results in an error: Screenshot 2023-04-04 at 03 18 23

I'm going to leave in all the resolutions.
